During my first year of medical school, I took out a small federal loan. The interest on the loan is deferred until I graduate from medical school. Well I recently graduated, and I received a letter a month or so ago stating that I owed them a payment, no surprise there. Well I logged onto the site a few weeks later to make a payment, and lo and behold their information says I am expected to graduate on 5/30/2009 and that I do not have to make any payments at this time. I called the 800 number and their automated menu provided the same information regarding my student status. Should I correct their mistake?
